LEMUEL C. KENDALL, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF ONE- HALF TO CHARLES L. YOUNG, OF SPRINGFIELD, MASSACHUSETTS.

SPECIFICATION forming part of Letters Patent No. 594,022, dated November 23, 1897.

Application filed December 15, 1896. Serial No. 615,748. (No model.) i

To all whom, t may concern.-

Beit known that I, LEMUEL C. KENDALL, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Freight-Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in freight-cars. In the previous application filed June 8,- 1896, and bearing Serial No. 594,728 I have provided a freight-car, especially adapted for a graincar, of a cylindrical form, the axes of said cylinder running at right angles to the line of the track upon which the car is designed to move. I herein provide an improved wheelfiange adapted to be used with said car.

In the accompanying drawings, Figure lis a side elevation of the car equipped with my device. Fig. 2 is a top plan view thereof. Fig. 3 is a section through myim proved flange, and Fig. 4 is a view showing a modified form of my device. Fig. 5 is an enlarged detail section.

The numeral l indicates a supportingframe, to which are attached the cylindrical car-bodies 2. I preferably attach these bodies so that they will rotate about their axes, and they are so illustrated in Fig. l, while in Fig. 4 they are shown immovably fixed with reference to the same. Vithin these car-bodies I propose to use the device claimed in my former patent or the means hereinafter described in order to keep the grain in place. The flanges 3 extend around the car-body and are made in the usual manner, while the flanges 4 are made with roller-bearin-gs. The flange 4 has in the sides thereof two annular grooves 5 and is adapted to rotate relative to an annular bearing 6, which is provided with similar grooves 7. Balls 8 lie partially within grooves in the flanges and their'cmplementary grooves in the bearings. In the form illustrated in Figs. l and 2 it is only necessary to have one of the flanges on the carbody of this latter description, this being provided in order to allow for the movement on going around curves. In the form illustrated the reciprocating rotary class, and in this event provide the shaft with a handle extending at right angles thereto, as shown in the drawings. This pump communicates with a rubber bag 12, and upon the frame is a lug 14, adapted to engage the handle of the pump.

At 15 is shown a safety-valve, of which any form desired maybe employed, that herein shown being of the spring-pressed type. With the rotation of the car-body the handle of the pump will strike against the lug and thus actuate the pump and force air into the bag. It is obvious that this construction will replace. any space caused by the settling of the grain and will maintain a constant pressure against the body thereof, thus holding it from being broken by the constant tumbling. In the form shown in Fig. 4 it is not necessary to show any device of this description, as the carbody does not rotate and the grain is not thrown about bythe motion of the car.

Suitable doors or manholes may be provided where deemed necessary in the car-body.

It is obvious that I have provided and set forth an improved grain-car which will readily move around curves or on straight tracks with the use of little power.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a grain-car, the combination with a cylindrical car-body, of flanges extending therearound adapted to roll upon a track, and inflatable meanscontained in said car and se-` cured along one end thereof whereby the space unoccupied by grain may be filled, and a safety-valve operatively connected with said iniiatable means.

IOO

within said trough provided with complementary grooves,andballs Within said grooves constituting a ball-bearing adapted to permit the rotation of the ange relative to the trough.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

LEMUEL C. KENDALL.
